[Octave-bug-tracker] [bug #55528] [MXE-Octave] graphics_toolkit gnuplot does not work

[Avinoam Kalma]

Follow-up Comment #7, bug #55528 (project octave):


>> addpath (fullfile (__octave_config_info__ ('fcnfiledir'), 'plot', 'util',
'private'));
>> __gnuplot_version__
error: you must have gnuplot installed to display graphics; if you have
gnuplot installed in a non-
standard location, see the 'gnuplot_binary' function


And I get also an error window with


The procedure entry point ScriptIsComplex could not be located
In the dynamic link library GDI32.dll.


Actually, the error message "error: graphics_toolkit: gnuplot version too
old." is misleading,
because the problem is that gnuplot is not functional.

If I copy gnuplot.exe to another directory, it works fine:


c:\Octave\Octave-5.0.1\mingw64\bin\tmp>.\gnuplot.exe

It seems that one of the dll's in directory Octave-5.0.1\mingw64\bin makes
gnuplot non-functional.
